Innate left-handers and those whose languages are written leftward thus share an unusual facility for left-handed mirror writing, an observation that may have implications for understanding hemisphere specialization in relation to handedness. It has been postulated that disruption of thalamo-cortical pathways may be the common underlying factor in these conditions.
Or, it may be a problem with perception, in which the brain becomes confused about how the letters should look, the second explanation posits.
Nevertheless, the high prevalence of mirror writing reported in healthy individuals and in patients whose languages are typically written and therefore also read from right to left is striking. The visual hypothesis, in which it is similarly envisaged that there are bilateral visual memory traces engrams in the brain, mirror writing albums nondominant usually right hemisphere engram being in mirrored form and again normally suppressed.
The purpose of this practice by Leonardo remains unknown, though several possible reasons have been suggested. These imaging techniques might prove valuable in studying mechanisms underlying mirror writing in left- and right-handers and in those whose customary languages are written in different directions.
In fact, not all cases of mirror writing are problematic. But doctors sometimes see people mirror write after a stroke that leaves them only able to use their nondominant hand for writing, said Sergio Della Sala, a professor of neuroscience at the University of Edinburgh. The spatial-orientation hypothesis, in which it is suggested that there is confusion in respect of direction and orientation of reading and writing, sometimes associated with spatial confusion.
This suggests that, although ideographic languages are extensively processed in the right hemisphere, it is less the structure and more the leftward direction of these languages that is important and that drives, or is driven by, the contralateral right hemisphere. Mirror writing runs in the opposite direction to normal and with letters reversed, and it is most easily read using a mirror.
In right-handed adults who write with their left hand, mirror writing can be produced at will and for fun, and it is undertaken by lithographers, printers, and others for occupational purposes. Furthermore, left-handers often find mirror writing particularly easy.
Mirror writing with the left hand has also been associated with diffuse cerebral disorders, including head injury, and various neurodegenerative processes, including Parkinson disease, essential tremor, and spinocerebellar degenerations. This finding cannot be attributed to population differences in handedness.
Leonardo da Vinci wrote most of his personal notes in mirror, only using standard writing if he intended his texts to be read by others. Matteo Zaccolini may have written his original four volume treatise on optics, color, and perspective in the early 17th century in mirror script.
Such studies in turn may further understanding of the links between hemisphere specialization, handwriting, and handedness. The characteristics of mirror writing, the circumstances in which it occurs, and many of the theories thought to explain it were reviewed over 70 years, 1 and subsequent clinical and theoretical aspects have been briefly reviewed more recently.Mirror Writing.

Activity: Mirror Writing Writing Backwards Write a message using Leonardo's mysterious backwards mirror writing style.
Leonardo's Private Notes. Not only did Leonardo write with a special kind of shorthand that he invented himself, he also mirrored his writing, starting at the right side of the page and moving to the left.
Only when he was. Writing letters backward and in reverse order, sometimes called mirror writing, may be a sign of a deteriorating brain, but in one woman's case, researchers found that the unusual condition was.
Mirror writing is formed by writing in the direction that is the reverse of the natural way for a given language, such that the result is the mirror image of normal writing: it appears normal when it is reflected in a mirror. It is sometimes used as an extremely primitive form of cipher.
Mirror-writing is the production of letters, words or sentences in reverse direction, so that they look normal when viewed in a mirror.
Some people may mirror-write intentionally; but unintentional mirror-writing is surprisingly common amongst young children, and in brain-damaged adults. Jamie Woon released his debut album in April The album gained popularity in Europe, peaking at #15 in the UK and #9 in Belgium.
